UrbanStems wants you to get all senti about your friends and family. (Psst, that’s Filipino slang for “sentimental.”)

The local, venture-backed flower delivery company teamed up with Brooklyn gift startup Tribute.co, buzzy Manhattan period underwear company Thinx and bidet startup Tushy for the #GratitudeChallenge, which asks people to post videos in which they talk about why they’re grateful for their loved ones, our sister site Technically Brooklyn reported. The video with the most likes gets a $1,000 prize package from all four startups. The contest ends Wednesday, Nov. 30.
